Domestic water piping

Piping overview

Figure 2 DHW piping

THERMAL Expansion tank — If a backflow preventer, check valve, or pres- sure reducing valve is piped on cold water inlet of water heater, you must install an expansion tank on cold water supply line to prevent normal thermal expansion from repeatedly forcing open T&P relief valve.

The T&P relief valve is not intended for constant duty, such as relief of pressure due to repeated normal system expan- sion. Refer to expansion tank manufac- turer’s instructions for proper sizing.

Failure to comply could result in severe personal injury, death or substantial property damage.

General applications

1.Figure 2 — This piping configuration can be used in most cases, except where local codes require special components or piping not illustrated.

2.Some codes may require the items listed as optional, such as a vacuum breaker on the inlet line, or re- circulation piping.

Massachusetts applications

1.For Massachusetts code applications, or as required elsewhere by local codes, install the fol- lowing options.

a.Thermal siphon on DHW inlet and outlet.

b.Vacuum breaker on domestic water inlet line.

c.Recirculation — Massachusetts code applica- tions require recirculation piping or heat-traced piping if the distance from the water heater to the furthest fixture exceeds 100 feet. See page 8 for details.
